Abstract (en)
[origin: EP0744840A2] A communication terminal in which the power consumption in an intermittent reception can be reduced magnificently. The state value of second spread code generating means (62) for next drive is set to register means (73) to operate timer (70), and first and second spread code generating means (62, 75) and receiving circuit are stopped to enter a sleep state. Then, if they are driven again by the timeout of timer, the receiving circuit is operated and the second spread code generating means is operated from the state value which has been set to the register means. Further, the intermittent receiving means (65) for operating the first spread code generating means from an initial state is provided. Therefore, in non-reception, the first and second spread code generating means can be stopped, so that the power consumption in an intermittent reception can be reduced magnificently. <IMAGE>
